Desna Culture fits the Tanged Points Culture standard perfectly. This culture is related to Tanged Points Culture in that it regularly yields shouldered points and oblique trapezes on flakes. Five types of single-barbed Havel-type harpoons were mapped. According to this mapping, Havel-type harpoons are divisions with three zones, which correspond to Swiderian, Ahrensburgian and Desnenian areas.
Thanks to up-to-date research on Magdalenian Culture in Poland we can now identify three settlement provinces: Upper Silesia, Malopolska and southeast Poland. Magdalenian settlements in Poland existed from Dryas I till Alleröd. Polish Magdalenian is a part of the Central Europe Cultural Province. Very interesting is Maszycka cave, where new material from different European territory was found.
A serious argument against the reach of Hamburgian Culture to the eastern Vistula is the position of material from areas to the east of the Vistula, the lack of any radiocarbon dates and the unclear geochronological context.
The author maintains that the soils formed by the Pomeranian Glacier during the Bölling Interstadial at the time of Hamburgian Culture stood under rising moisture and were not yet lixiviated enough. The main food sources of reindeer, especially reindeer-moss (Cladonia rangiferina) and dwarf birch-trees (Betula nana), require a sandy, dry, non-calcareous soil and therefore could not flourish in the highly calcareous moraine clay.
Because the reindeer herds probably avoided the plains in eastern Germany between Schleswig-Holstein and the Middle Oder during the Bölling Interstadial, it is highly improbable that the discovery of any sites of Hamburgian Culture in this area could be reckoned with in the future.
